Johnny G's 3.4 litre V6 MR2 Turbo


Recommended Posts

The 5VZ-FE monster built lump thats about to grace my engine bay has come all the way from Canada (Built by Johnny Riglietti of Sea2Sky Tuning) and will support crazy BHP - hopefully. Just needs a bit of detailing to make it look the part but trust me this is one seriously built motor.

 

image

 

Headwork...

image

 

This is going to be a mammoth build, and promises to be the highest BHP machine ever to leave Woodsport, by quite a bit!

 

 

Fuel pumps

image

Both walbro pumps are now installed in the tank.

 

In other news Paul started extending the rear light harness, this is so he can relocate the fusebox in the engine bay to make room for other interesting stuff http://forums.twobrutal.com/images/smilies/smile.gif

Chargecooler

Part of running a huge BHP turbocharged v6 monster is keeping things cool, more importantly the intake charge, so some serious cooling was called for, prepare to meet the chargecooler from hell....

 

image

 

Im told this monster, nicknamed "johnnys fridge", will support a 1000 BHP application, and keep the intake temps down no matter what we do.

 

Its so f'kin huge this was pretty much the only place we can mount it was in the boot as the engine bay isnt big enough for both the engine/turbo and cooler, and thats without all the plumbing running between them all! so this location isnt out of choice, its the ONLY place it will go, but its a nice neat "out of the way" place for it that can also be supplied be additional side vent air cooling if need be....

image

 

We just sit staring at it sometimes in awe http://forums.twobrutal.com/images/smilies/icon_lol.gif the outlet pipes are 4" diameter on that b'stard!

 

Here is the access hole Paul cut in the rear wall for the CC pipes to enter the engine bay,these need fine trimming and dressing but you get the idea....

image

 

So thats the fridge's position mocked up,want to see the CC again? ok..... http://forums.twobrutal.com/images/smilies/icon_lol.gif

When I first showed Paul this thing he was shaking his head in disbelief!

 

Detailing

Paul turned his attention to the engine detailing, starting with cam covers, painted in Toyota Royal Sapphire Pearl (same colour as my Supra).

image

 

And here is the engine in its current state. Note its running the stock injectors and fuel rails for now,this is so we can bed the engine in with no boost. When we are happy enough for the boost to be brought in the fuelling will happen and in very large volumes!

 

image

 

Also Paul welded the oil return into the sump.

image

 

 

image

 

image

 

The engine bay was given a respray, it was in a bad state and no mistake and afterwards, the bay has a nice monster 5VZ-FE hanging in it.

Plumbing

Paul got this huge turbo mounted where it keeps everything happy. Its huge.

 

Paul made a preliminary bracket that takes the bulk of the weight, he's also going to add various support brackets as it takes shape, but for now this has the turbo sitting where he wants it.

image

 

image

This build is more function over form,not much fancy detailing work going on but we still want to keep things looking reasonably pretty!

 

The turbo is puroseful though.

 

Garrett GT4094R

Compressor

67.8mm inducer

94.0mm exducer

52 trim

0.72A/R

 

Turbine

77.0mm Wheel Diameter

78 trim

1.06A/R

Free floar

 

0.95A/R Turbine housing.

 

Suffice to say, that this will be pushing around 65lb/min which we're hoping will be north of 550bhp, but very drivable with positive boost from 2400rpm and holding easily to the red line.

 

This is the main plenum tube, its 100mm diam, and should be around 400mm long, that will give us a volume of around 3.1 ltrs excluding the runners....

image

 

Behind that you can make out the plate thats going onto the centre plenum, 6 weld els will join plenum to plate. They are tricky little blighters to fit in a row, Paul is going to have to seam weld them all together.

 

So there's a ton of fabrication work to do to this plenum alone, and he's also got to sort idle speed control along with a million other headaches I have given him, deepest joy.

 

He managed to fabricate up the exhaust manifold to turbo pipes, kept them nice and flowing. Just waiting for a 2nd turbo flange to arrive before the pipe is completed.

 

image

Paul fabbed up the Tial external waste gate,this is positioned in such a way that we can easily plumb it into the turbo down pipe, but I've told Paul that its to have a screamer pipe fitted, still at least the choice is there either way now to have a recirculating pipe.

 

image

 

image

 

Also made a start on the plenum. He's making this out of mild steel, here are the intake runners welded on,these have been extended.

image

 

image

 

Its a huge amount of work but its great fun!

 

Here is the plenum bit, obviously in its raw state....

 

image

 

And it mocked up in situ....

 

image

 

Tell me that isn't the scariest f'kin thing you ever saw!!

 

image

 

I promise it will look better when its finished!

 

image

 

Oh yes and here's the throttle body, a 90mm thing off something big!

 

image

 

Overview of where we are now, can you smell the BHP???

Paul seam-welded the plenum up, he had to make sure the welds were as perfect as he could make them, one pinhole and it will lose boost.

 

Pretty good i reckon.

image

 

Then the plenum section was seam welded on, again taking utmost care with every weld.

image

 

Then attention turned to the end plate, he added two unions here, one for brake servo and the other for boost gauge/map sensor etc. He can add more later if need be.

 

image

 

Next came the idle speed controller, we are using a 3VZ-FE ISCV for this engine. On goes the adapter plate.

 

image

 

And then a trial fit of the plenum in the bay with ISCV.

 

image

 

He also dummy rigged the throttle body onto the plenum for intake pipe fabrication, there's a custom throttle body plate on its way.

 

image

Paul did get some things done, this is the chargecooler to TB pipe, it houses the BOV and also the ISCV bypass pipe.

 

image

 

So we just need the silicon couplers and some paint on these parts and it can be fitted.

 

Paul also found a home for the air filter,its going to be mounted right in the passenger side vent, you don't get colder air than that.

 

image

 

Also he got the turbo to chargecooler pipe fabbed up, again needs paint but it was a tricky pipe to navigate around the engine bay.

The throttle body flange arrived from AH-CNC, cheers mate, work of art as per usual.

 

image

 

image

 

In hindsight we could have made the plate a few mm bigger, Paul's welds are just encroaching on the nice engraving Adam did, but its worked out OK.

OK! Another mental day of turbocharged 5VZ'ery. Paul got the charge cooler couplers dummy fitted and all pipework to and from the turbo/throttle body sorted.

 

image

 

image

 

Everything is really starting to come together now. He also finished off the wastegate section.

 

image

 

He spent a few hours on the exhaust downpipe, starting with this pipe running along the front of the engine.

 

image

 

From here it does a sharp 90* downwards using this.

 

image

 

Here it is under the car.

 

image

 

So this will give an identical routing for an Mr2 exhaust system from here on in, another angle of the exhaust outlet...

 

image

 

And a few sexy overviews of the whole bay now,nothing especially detailed yet but looks mean as hell....

 

image

 

image

 

We really are pushing the boundaries with this build, I don't think anyone in the UK MR2 scene is doing anything quite as mad as this!

Some nice pictures ..

 

image

 

image

 

The harness was made up, trimming down the original one

image

 

Then it was time to put the injectors in, 1000cc

image

 

And then all fitted!

image

 

Also added a flexi to the turbo inlet pipe, it was tricky to remove and it will also help prevent cracking.I also got it all wrapped and ready for the final install.

 

image

image

 

Aeromotive RR-FPR installed and mounted nicely

image

image

 

Custom plenum all prepared, painted and installed now

image

image

 

The engine bay is getting fuller by the day, all heater, turbo and rad lines are now done, as well as a custom coolant filler assembly.

image

 

99% of the chargecooler set up in the boot is now finished, i had to make another adapter so that a filler neck could be added and i still have an expansion reservoir to add but this is nearly there.

image

 

Custom fitting of a MK2 N/A alternator, brake servo hose and one way valve fitted, ISCV bypass hose added,throttle body coolant lines fitted and fuel return line plumbed.

image

 

Paul wired up the ignition amplifier, the injector resistor pack, the starter relay, alternator loom made from scratch, idle speed control valve harness made and all signal wires for the dash installed. He labelled the whole lot up too so Ryan from 2BarTuning's work should be simpler.

With the driveshafts fitted and rear ABS hubs installed (GT-S spec car did not have ABS but we need them for the traction control which is built into the Solaris S6 ECU ), it was time to turn attention to the massive brake upgrade this car is getting.

 

On the rear we are using supra discs which are going to be mounted on specially made hat spacers that will sit between the hub and disc, this gives us the correct offset to clear the hub and calliper. Then it's planned to mount an MR2 rear caliper onto this disc.

image

 

And here, behind 18x10" wheels +ET20

image

 

Now to compliment the mad rear upgrade how does this grab you on the front.

image

Yes, they're 911 Turbo calipers!

 

And again, behind an 18x8.5" +ET20 wheel...

Paul has now plumbed up the breather system via the oil catch can. This was tricky because he had 8mm, 10mm, 12mm and 14mm ID fittings on everything and had to make it all plumb together. We got there in the end. Needless to say ordering parts for a 5VZ turbo is not simple!

 

We have also redone the fuel pressure regulator, the fittings it came with failed during start-up so i have had to make those from scratch and used some Teflon coated braided fuel line as well.

 

Work has also started in plumbing up the chargecooler system, the pump is now wired and the pipes run via the drivers rear inner wing as there is simply no safe route via the engine bay.

 

Here is how she looks now, still a lot of tidying up to do....

Some more little bits done in the boot. The Charge Cooler expansion bottle is now plumbed.

image

 

And a bracket made for the Solaris S6GP ECU

image

 

The harness still needs wrapping but we can't do that until the ABS sensor wires are all connected.

 

I've kept the road-testing to a minimum and got it in when I could, thanks to the great English weather. Been out in it today (29th Dec) and it was a little jerky on the basemap.

 

Luckily, I had a friend come and visit me, some of you might have heard of him, his name is Ryan Griffiths of 2Bar Tuning

 

Yes, ladies and gents, my fabled white beast is now mapped!!!

 

Conditions were not the best, it was cold, but dry at least. So, we did around town "manners" driving. Some motorway "manners" driving, then we hit the boost...

 

0.2bar @ 1800rpm

0.5bar @ 2400rpm

0.9bar @ 3100rpm

1.1bar @ 3300rpm

 

Because of the conditions, etc we just mapped in 5500rpm and 1.1bar of boost, but rest assured, it's obscene. It's MENTALLY quick.

 

Ryan, the mapper, said it's VERY QUICK and has a lot more to come from a relatively conservative road map - it's the best Birthday present I've ever had!!

 

He was impressed with the work on the car and is looking forward to see what it yields - as we all are.

 

The way it gathers pace in 5th gear is just sensational. The noise of the turbo and wastegate mental, mental chicken oriental!

Incredible! (Very well documented via your photos & effort that has gone into the descriptions & story-telling, too.)

 

How does the weight of the engine compare to the original block, and what about the weight distribution now? Will you need to change any suspension bits/ratings to make it all 'work' together again?

 

Fantastic machine, when do I get to admire it up close in the metal and see it in action on a track somewhere? :)

Cheers, Steve. Very kind words there! It was Paul Woods who did all of the photography and the installation, I just paid :)

 

For the next couple/three months, I'll be running it around, putting miles on it then I'll be heading to see Ryan at SRR where the boost can get wound up to maximum - whatever that will be - and the rev limit increased to 7500. Once we've got that out of the way, it's a few little pieces of cosmetic work (interior), then it's good to go!

 

Looks amazing, and well done to the two of you for doing such an ambitious build. Will look forward to hearing how it performs. :)

 

Cheers, Andrew, I'll hopefully get a few videos against jevansio when his chariot is running!

That is pretty crazy! Respect to all the work you put in though. I've seen pics of mr2's with v6's in them and that looked a tight squeeze, never mind with a turbo stuck on the side of it, I bet you had a few head scratchers with that:)

 

It was Paul Woods of Woodsport who had the head scratches! Many times he said in his unique Irish/Geordie twang that it was going to be too tight and couldn't be done :)

I googled to see what that engine was fitted to originally and found this Wikipedia article which claims...

Output is 190 hp (142 kW) at 4800 rpm with 220 ft·lbf (298 Nm) of torque at 3600 rpm. It has a cast iron engine block and aluminum DOHC cylinder heads.

 

The 5VZ-FE was also far overbuilt for its intended application & many stock, semi-modified non-turbo and non-superchargered engines continue to be considered one of the more reliable small truck or SUV V6 engines ever made. A handful of built versions exceed 900 hp (670 kW), and some stock engines can produce 450 hp (336 kW) or more

Now that's a build thread. :D Was just expecting a start, some ideas and details.

Nah. Not Johnny G. Let's put virtually the whole build in in a oner. Bam. :blink: :D

Well done to you and Mr Woods great work. Insane idea. I reckon Mr Woods must be thinking you're a few sandwiches short of a picnic. ;)

Fair do's to him for getting that in though. :thumbs: I'm looking forward to seeing that completed Johnny. Great stuff. :)

Fantastic build. I would personally change the HKS filter but that's about it. During the build it just looks monsterous, totally built to do something and not just look the part.

 

Fantastic effort from Paul, absolutely outdone himself.

 

Oh, did you not say the car was blue? Read it wrong, that's the supra lol.

Is it just me or is anyone else trying to say 'It can't be done' in his unique accent :D

 

Great project Johhny. Can't wait to see this in real life. I love the fabrication work that's been done. Top marks :thumbs:
